SULKY -PLOW.

SPECIFICATION forming part of Letters Patent No. 299,020, dated May 20, 1884.

Application filed November 1, 1883.

T0 (tZZ whom it may concern:

Be it known that I, CHARLES SOHWEER, a citizen of the United States'of America, residing at Eldon, in the county of \Vapello, and State of Iowa, have invented certain new and useful Improvements in Sulky-Plows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to sull y-plows; and it consists in the improved construction fully described hereinafter, whereby the elevation and lowering of the plow proper is readily effected by the driver from the seat, the vertical adjustment of the plow-supporting frame with respect to the carrying-frame easily secured, and the manipulation of the guidewheel from the seat secured.

In the accompanying drawings, Figure 1 is a plan view of a sulky-plow constructed in accordance with my invention. Fig. 2 is a side view of the same. Figs. 3 and 4 aredetailed views, and Figs. 5 and 6 are enlarged detail views.

The carrying-wheels A B are mounted and turn on the axle O. Abar, a, is keyed on the axle near each wheel AB, and projects toward the forward end of the plow to support the ends 11 of a transverse yoke-bar, D, the said yoke-bar D being bent in the center to form the vertical portion E, the lower end of which is perforated to receive the end of a rod, 0, secured to the mold-board F of the plow, and threaded at its end (I to engage a securingnut, e. e

The plow proper is secured tothe lower end of the vertical curved portion G of the beam H, to the forward end of which is. secured a bracket, I, the earsf of which are perforated for the passage of a neck, .I, of a yoke, K, carrying a caster-wheel, L.

Abeam, M, is secured at its forward end, h, to the forward end of the plow-beam H, and extends rearwardly back of the axle O to support at its extremity 45 the operators seat N. The said beam M is braced and supported by being located between vertically inclined (No model.)

- braces j j, secured at their lower ends to the axle O and perforated for the passage of a securing-pin, 70, which also passes through a perforation therefor in the beam M. The lower ends of the vertically-inclined braces j j are spread some distance apart, for the purpose hereinafter described.

A diagonal brace, O, is secured at its forward end, It", to the side of the bracket I, its rear portion, 1', being curved approximately in a hook shape, the terminal portion m of which passes through a yokebracket, a, bolted to the upper portion of a bar, a, secured at its lower end to the end I) of the yoke-frame D, and lying almost parallel with the bar a, located on that side of the machine, a set-screw piercing said yoke-bracket n to rigidly secure the curved portion of the brace O therein. One of the ends I) of the transverse yoke-bar D passes through aperforation therefor in the brace O at a point where the hook portion thereof commences. A second diagonal brace, P, located on the other side of the plow-beam H is bolted at its front end, 2, to the bracket I, and extends back and terminates in a hook similar to that of the brace O,which passes through a yoke-bracket secured to the side of a second bar, a, secured at its lower end to one end Z) of theyoke-framc D, and lying almost parallel with the bar a, Fig. 2, located 011 that side of the machine, a set-screw being provided for the said yoke-bracket for rigidly securing'the curved portion of the brace P. The brace P is also perforated for the passage of one of the ends I) of the transverse yokebar. The upper end of the neck J of the caster-yoke K has centrally secured thereto a horizontal bar, Q, which is perforated at its ends 1' for the attachment of cords or cables .9, which extend back and are each secured to the upper end of a vertical bar, t, centrally pivoted on one end, a, of a horizontal rod, B, rigidly secured at its center to the upper ends of the vertical braces j j. The lower end of each bar it terminates in a stirrup, S.

The clevis Q has hinged thereto a short perforated tongue, T, which is adapted to be clamped to the draft-tongue proper, U, of the machine.

The diagonal brace 1 consists of two secelongated slot-s P, which permit the extenv a, perforated at its head.

sion of said brace P, the sections being firmly clamped with respect to each other by means of bolts or nuts 19.

A sleeve, 0, Fig. 1, rigidly secured on the shaft 0 and at one side of one of the vertical braces j, is provided with a stud, 0, upon which is pivoted the elbow of a bell-crank lever, 0, one portion, 0, is bent-to permit its end to normally rest upon the axle O. The other portion of the bell-crank lever extends out at right angles to the rear of the axle, and is perforated at its end for the engagement of the hooked ends of two rods, D D, respectively, extending off toward each side of the machine. Portions c of each bar a extend downward in an inclined direction at the rear of the ends of the axle O, and each carry a bracket, a, within which is pivoted a dog, The perforation of the dog a, on the side of which the diagonal brace P is located, is engaged by the outer hooked end of the rod D, while the perforation of the dog located on the side of the machine on which the brace O is arranged is engaged by the outer hooked end of a rod, D; the other end of which is pivoted to one end of a bell-crank lever, D, pivoted at its elbow upon a stud, w, projecting from the base 20 of a hand-lever, \V, which iskeyed on the shaft 0.

Near the upper end of the lever V is pivoted a small handle, W, connected to which is the upper end of a rod, W, the lower end of which is looped to receive the upper ends of links w w, the lower end of the link w being connected to the end, not before referred to, of the bell-crank lever D, while the other link, w", is connected at its lower end to one end of a bell'crank lever, D also pivoted at its elbow upon the stud w, the other end of the said bell-crank lever D engaging the end of the rod D? nearest the handle W".

Leaf-springs s bearing on the inner sides of each extension at of the bars a and between the lower portion of each dog-a, serve to nor mally throw the upper ends of the said dogs outward in the direction of the extremities of the axle O.

In the lower part of the vertical portion E of the transverse yoke-frame D is a slot, (shown by dotted lines in Fig. 2, and full lines, Fig. 6,) within which is pivoted the rear end of a pawl, having a lip, y, which bears against the rear face of the vertical portion E of the yoke-frame D. The pawl 11 has ahead, 3 at its extremity, which carries at one side a horizontal pin, 1/.

A curved rod, 2, is secured at one side of the yoke-frame D, and extends so as to permit its threaded end 2 to pass through a perforation therefor in the beam H, in which position it is securely clamped by nuts 2 The carrying-wheel A being mounted on the side of the machine in which the plowed land is, the said wheel is furnished with a broad auxiliary tire, A, which prevents said wheel from sinking into the loose ground.

When it is desired to elevate the plow so as to clear the ground, the handlever W is moved back, turning the shaft 0 rearwardly and lifting the outer ends of the bars a a, which elevates the yoke-frame, plow proper, and parts connected thereto, so that the head 37 of the pawl y strikes the shaft 0, and, being raised, drops over in engagement with said shaft, suspending the plow in an elevated position. The pin y" of the head when said head engages the shaft 0, bears on the upper side of the portion 0 of the bell-crank lever C".

'When it is desired to cause the plow proper to descend to its working position, the handle W is forced toward the lever W, causing a vertical movement of the rod VW and links 10 w, the link w" operating the bell-crank lever D to draw on the rod D thereby tilting the bell-crank lever (l on its pivot, and causing its end 0 to raise the pawl 3 from its engagement with the shaft 0, and permitting the plow to drop to a working position. The lever Wand appurtenances, and the rods, dogs, and bellcrank levers being all connected together, the leaf-springs effect the return of the dogs to their normal position and the return of the extension O" of the bell-crank lever C to its hearing upon the axle. By moving the lever WV forward and rotating the axle in a direction reverse to that above described, the bars a a are thrown downward and cause the upper ends of the bars a tobe also moved downward toward the dogs a which engage the ends of the said bars a and hold the carriage in itse1evated position, the plow proper and yoke frame having served as a fulcrum for such elevation of the carriage. bars a on the curved ends at by means of the clamping-yokes n and set-screws of the braces O P, the said bars are caused to elevate the carriage to a greater or less degree before they are'engaged by the dogs a By adjusting the extension-brace l? so'as to be of greater or less length, one side of the carriage can be turned to or from the land side more than the other, which is desirable where the mold-board is to enter the soil at an incline.

By operating either one of the bars 16, the movement of the guide-wheel to the right or left is effected.

The arrangement of the clevis described permits its ready connection to the drafttongue, and a connection that in no way communicates to the plow the movements of said tongue.

From'the foregoing description it will be apparent that the sulky-plow described is effective in operation, and may be easily manipulated to secure the various adjustments desired.

I claim- 1. The combination, in a sulky-plow, of the carriage having a main axle and carryingwheels mounted 011 the ends thereof, a frame pivoted to the carrying-frame and supporting the plow proper, a pivoted pawl located at the lower portion of the plow-supporting frame, devices located on the main frame for raising By adjusting the said IIO the plow-supporting frame, so as to permit carriage, a plow-supporting frame pivoted said pivoted pawl to engage the main axle and suspend the plow-supporting frame, and a bell-crank lever pivoted on the main frame, and having one portion located 011 the point of the main aXle which the pivoted pawl engages, and connections on the main'carriage connected to said bell-crank lever to move the same upon its pivot, substantially as and for the purpose set forth.
